WIRE-BENDING MACHINE.

Specification of Lettersratent. Patented July 16, 1918.

Application filed May 17, 1916. Serial No. 98,110.

To all whom it may concern! Be it known that I, JOHN WINSOR, a citizen of the United States, residing at Corry,

in the county of Erie and State of Pennsylvania, have mvented certain new and useful Improvements in Wire-Bending Machines, of which the following is a specification, reference being had therein to the accompanying drawing. This lIlVGl'itlOll' relates to wire bendmg machines and is an improvement upon Patent #1,113,104, dated October 6, 1914, issued to John E. Dean, the object being to provide a double guideway in order to form a twopoint suspension for the shuttles, whereby friction will be reduced as the shuttles are supported in the guideway in such a manner :that the samecan be driven with less power.

Another object of my invention is to pro-' vide a wire bending machine in which the shuttles are mounted between spaced plates having guideways formed therein in such a manner that the wire carried by the bobbins gofthe shuttles will be prevented from getting tangled in the gearing when the wire accidentally breaks, thereby overcoming the disadvantages now existing; In" machines of this character.

Another object of myinventionis to provide a wire bending machine in which a pair of figure-8 guideways are employed in which the bearings of the shuttles are mountedin such, a manner that the shuttles are supported in the guldeways so as to eliminate the drag of the shuttle when being driven by the driver, as is the caseof wire bending machines now in use in which a shuttle travels 111 a single guideway. v

Another obj ect of my lIlYGIltlOIi is to pro vide a wire bending machine in which the carrying capacity of the bobbins can be increased by supporting the shuttles at two points thereby saving the time of refilling the bobbins of the shuttles.

7 Another and further object of my invention is to provide novel means of constructing the guideways by supporting the central plates forming the inner edges of the guideways in such a manner that they will be sup .ported in the proper position without interfering with the driving of the shuttle driver or the movement of the shuttle of the guideways. l

partly in section, of my improved construc- Another and further object of my invention is to provide an improved construction of "driver by forming the same of a driving sleeve provided with a pair of disks having notches adapted to receive trunnions of the shuttles so. as toobtain a two-point contact drive for the shuttle in order to carry the same through the guideways in such a man- "ner that friction is greatly reduced.

Anotherand further object of my invention is to provide a wire bending machine in which a greater number of shuttles can be employed in connection with the figure-8 guideways so as to form a multiple wire stay.

Other and further objects and advantages of the invention will'be hereinafter set forth and the novel features thereof defined by the appended claims. I r 4 In the drawings, 7

Like nun'oer'als ofrefere'nce refer to like parts in the several figures of the drawing.

In carrying out my invention, I employ a base plate 1 mounted. on legs 2 which are preferably provided with bearings 3 in which a driving shaft 4 is'mounted having a ranged non-rotating bearing shafts 10 and 11, fixed in position with the aperture of theiheaids'by set-screws 12.

'-*Mounted""o11 the bearing"'shaft 11 is gear 13 which meshes with the gear6, and

carries a gear 14 whioh meshesswith 'aagear 15 carried by the bearing shaft as clearly shown in Fig. 2. By this construction as the shaft 4 is driven by the pulley, the gears 14 10. and 515 .arearevolved xthrough the-driving connection with the gears 6 and 13 which construction is substantially the same as v .7 Shown an i edin the...Dean -patent abovereferred to. *iI Q 1 d on the opposite end of the base plate'lare spaced'guide plates 16 and 17 which are provided \with base portlons adapted to be bolted to 'the'base plate 1 as,-

' c'learlyvshown in Figs. 1 and 2, each plate 201 being providedwith acut-outportion tov 'form;'tlie outer. peripheral; edge of-a guideway IS-whichwis substantially thefshape of "1 f 'afigure 8.

The hub portiohsltl" and 20 receive 80 thesh a'fts l0 and 11, andjare secured in position upon said shafts bypins 21 passing I thrjoughthe; hub portion and shafts as "shown Fig. 5.

Froni'th'evconstruction thus far described,

it will be seen that I have provided a wire *bend'ing'machine in which a pair of spaced guideways are arranged on the base plate 1 having-n pair of drivers mounted between the guldeways .111 such a manneras to cooperate with the" shuttles mounted in the guide- Ways as willbehereinafter fullydescribed,

' each driverbeing drivenfrom-the; driving gear of themachine suchamanner that the centralfgulde plates forming the inner edges of the guideways are supported independent of the driving sleeves so as to allow the drivers to rotate freely :in-sucha manner as not to interfer'iwith the movementof the shuttles in the guideways.

In the construction of a wire bendin machine herein shown,prov1s1on 1s for "employing five shuttles, as:each-dr1ver,

which-is composed of a pair of driving disks, 9 is provided with five/notches soEas -to cooperate with'theshuttles and in Fig. 5 I have shown five" shuttles in position-within the iguideway, which: shuttles are adapted to be forcedthrough the guide-way so as to 5 traverse the figure-8 guideway, and thus wrap thewire alternately around thepins 34 in: substantially the same manner as above referred to. v 0

"My improved construction of shuttle comprises a "casing '35 having means for supporting a bobbin 361Carl'ying the .wire 37 therein, saidflcasing havingoppositely disposed trunnions 38 and 39. whichflare provided with antifriction rollers 4:0-to recelve the drivers in order to cause the shuttles to move .in the guideways as will be hereinafter fully described.

The trunnions 38 and 39, are provided With*gui'de-plate zs ll and 42 from which are spacjedfguide-plates 43' and A by-pins 46 and 47' carryingantifrictionrollers418 adapt- .ed'to travel in the'guide-ways'of the plates 16 and 17 in order to form a two-point sus- 5 pension for the'shuttleso' as to -allow the same to be driven freely through thefguideways without any drag caused by the sag ging'of. the shuttle, from the .weight of the bobbin'mountedutherein, and I have found by experimenting that byemploying a twowire extending through an opening eformed in the-outer guide-plate 13 from which it passes to the tension wheel 47 upon which it is wrapped a suflicient number of times to prevent any slipping. The wire then passes from'the tension wheel 17 which is constructed" in any desired manner between grooved pulley 48"to the pins of the guideplates.

' From the foregoing description, it will be seen that, I have improved the general construction of the Dean patent by providing the machine with a pairof double figure-8 guideways between which a number of shuttles are suspended in order to obtain a twopoint suspension for each shuttle so that the weight of the shuttle and wire carried by the bobbin within the same will be supported at two points, which increases the life of the bobbin and allows the same to run freely through the figure-8 guideway. It will be.

seen that I have improved the general construction of driver by providlng a driver formed of spaced notched disks which are guideways.

adapted to engage the trunnion of the shuttle casing, at each side, between the 811513611- sion points so as to carry the shuttle through the guideway in such a manner that friction is greatly reduced. It will also be seen that I have arranged the shuttles between guide plates forming the guideway in such a manner that the guide plates form guards so as to prevent the wire which may become accidentally released from the bobbin from becoming entangled in the gear of the machine.
